The first tangible evidence of the smart grid in Minnesota is coming this summer, and it looks like a small, black mailbox.
The box, called a “synchrophasor,” is a high-tech sensor that monitors the flow of electricity humming across hundreds of miles of highvoltage transmission lines.
By sending more information faster, the devices could help avoid catastrophes such as the blackout that left much of the Northeast in the dark in 2003, grid operators say.
When these “phasor measurement devices,” as they are called, are locked in place along transmission-line routes, an avalanche of data will arrive at a NASA-like control room in Carmel, Ind., a suburb of Indianapolis, and its backup on the edge of St. Paul’s Energy Park.
